b. 47-49

composition: Op. 24 No. 4, Mazurka in B♭ minor

Without any marks in A (→GE1FEEE)

Staccato dots in GE2 (→GE3)

..

Lack of dots in bars  47 and 49 in A (→GE1FEEE) most probably results from Chopin's oversight. When one compares the accompaniment in five similar fragments (bars 13-17 and analog.) one can see that the omission of those dots is accidental.

A shorter slur in GE1 (→FE)

..

Against the notation of A, in GE1 (→FE) the slur mistakenly ends on the semiquaver. The correct version was restored in  EE and GE2 (→GE3).

Chord notation in A (→GEFE)

The notation of  EE
